Definitions
- the particulate immobilized lipase according to the invention with macroporous silica or silicates as a carrier material is characterized by the fact that more than 90% of the particles have particle sizes between 100 and 1000 ⁇ m, wherein more than 80% of the pores in the particles exhibit a diameter between 10 and 45 times the diameter of the lipase globules, and wherein the water content of the particulate immobilized lipase is between 1 and 20%, preferably between 2 and 20%, more preferably between 5 and 20%.
- the invention is exclusively directed to particulate immobilized lipases, and lipases are quite extraordinary enzymes in the sense that the enzymatic activity is functioning on an interface between two phases, meaning that the immobilization of the lipases is a very delicate problem, which highly limits the utility of known immobilization techniques in the field comprising lipase immobilization, vide J. lavayre et al ., Preparation and Properties of Immobilized Lipases, Biotechnology and Bioengineering, vol. XXIV, pp. 1007 - 1013 (1982), John Wiley & Sons.
- the term "macroporous" means that the pores are at least 250 ⁇ in diameter.
- the pore diameter is measured by means of the B.E.T. method.
- the carrier material used in the immobilized lipase according to the invention consists of at least 65% weight of silica and/or silicates, preferably at least 90% by weight of silica and/or silicates.
- silica or silicates means genuine silica or silicates, i.e. silica or silicates, which are not derivatized.
- the diameter of the lipase globules can be measured by means of X-ray diffraction analysis and other methods, as indicated in "Biochemistry" of Albert L. Lehninger, 1970, Worth Publishers Inc., page 142 - 143.
- the diameter of the lipase globules is generally around 50 ⁇ .
- the particulate silica gels described in the Grace information leaflet SG BC 1E/June 1987 (from Grace, Grace Plaza, 1114 Avenue of the Americas, New York, N.Y. 10036-7794) are well suited for the purpose of the invention, as most of them have pore diameters of 500 ⁇ or above.
- silica gels can be used for immobilization of cells and enzymes, there is no indication in the leaflet whatsoever that the silica gels can be used for immobilization of lipases, and lipases are exceptional enzymes which in comparison to other enzymes exhibit unique characteristics in regard to immobilization, as explained earlier in this specification.
- EP patent No. 147,914 is described an immobilized lipase preparation on which lipase is immobilized on a glass carrier with particle size 30-45 mesh and an average pore size of 400 ⁇ .
- a coupling agent of the organotitanate type is used for the production of the immobilized lipase preparation.
- the immobilized lipase according to the invention more than 80% of the pores in the particles exhibit a diameter between 12 and 40 times the diameter of the lipase globules. In this interval of pore sizes the expressed lipase activity, measured in BIU/g, is especially high.
- the lipase is a thermostable lipase.
- the immobilized lipase can be used in columns operating with high temperature, whereby at least two advantages are obtainable: in the first place it is possible to use the immobilized lipase, e.g. for interesterification, without a solvent, due to the relatively low viscosity of the reaction mixture, in the second place the reaction rate will be relatively high, and in the third place the diffusion rate of substrate and products inside the pores will be increased.
- the lipase is produced by cultivation of a microorganism containing a gene encoding for and expressing a lipase derived from a strain of Humicola species, Candida antarctica or Rhizomucor miehei . These lipases have been tested, and they all perform well at high temperature in a column.
- the invention comprises a method for production of a particulate immobilized lipase according to the invention, wherein an aqueous solution of a microbial lipase is contacted with a particulate carrier material, which is macroporous silica or silicates, in which more than 90% of the particles have sizes between 100 and 1000 ⁇ m, and in which more than 80% of the pores in the particles exhibit a diameter between 10 and 45 times the diameter of the lipase globules, during a period of time sufficient to bind the wanted amount of lipase to the carrier material, whereafter the thus formed particulate immobilized lipase is separated from the aqueous phase and the separated immobilized lipase is dried to a water content of between approximately 2 and 20%. It has been found that a wash of the particulate immobilized lipase between the separation thereof from the aqueous phase and the drying thereof is advantageous.
- a particulate carrier material which is macroporous silica or silicate
- the period of time which is sufficient to bind the wanted amount of lipase to the carrier material varies from lipase to lipase, and it can range between a few minutes and a few days.
- the pH during contact between carrier material and aqueous solution does not deviate more than 1 pH unit from the optimal loading pH of the lipase in question in regard to expressed lipase activity.
- the expressed lipase activity measured in BIU/g of immobilized lipase, is as large as possible.
- the separation is performed by simple filtration. This is the simplest and cheapest way of performing the separation.
- the invention comprises a use of the immobilized lipase according to the invention.
- the use comprises a method for interesterification of fats, wherein liquid fats or fatty mixtures, including free fatty acids or fatty acid esters, are contacted with the immobilized lipase preparation according to the invention, a method for hydrolysis of fats, wherein triglycerides and water are contacted with the immobilized lipase preparation according to the invention, and a method for synthesis of glycerides or other fatty acid esters, wherein a mixture of glycerol or substituted glycerols or other types of alcohols and free fatty acids is contacted with the immobilized lipase preparation according to the invention.
- no solvent is necessary but a solvent can be used, if desired.
- the uses may be carried out continuously, e.g. in columns, or batchwise.
- the lipase activity unit (LU) is determined as described in the publication AF 95.1/2.GB of 83-01-03, obtainable from Novo-Nordisk A/S, Novo Allé, DK-2880 Bagsvaerd, Denmark.
- Fig. 1 illustrates the dependency between expressed lipase activity (BIU/g) and pH during loading of a lipase on carrier materials with different pore sizes.
- Fig. 2 shows the logarithm to the flow rate versus time for a lipase on carrier materials with different pore sizes.
- the data on Fig. 1 originated as follows.
- the silica carrier which is a carrier product from Grace described in Biocatalyst Supports SG BC 1E/June 1987 is washed with buffer at the pH to be used during the following lipase adsorption step, i.e. at pH 4, 4.5, 5, 6 and 7, vide Fig. 1, for half an hour and filtered.
- the wanted amount of lipase which is the lipase activity sufficient for generation of a loading of 186.000 LU/g is dissolved in 5 ml of deionized water and added to 1 g of carrier.
- the lipase is produced as indicated in Example 1 in Danish patent application no. 4417/86, i.e. by means of Humicola lanuginosa .
- the pH value is adjusted and the carrier and the lipase solution is slowly agitated by rotation for two hours followed by vacuum filtration.
- the filtrate is analyzed for hydrolytic activity (LU/ml) in order to determine the amount of adsorbed (loaded) lipase.
- the immobilized lipase is air dried, the moisture content is adjusted to 10% by weight, and the sample is analyzed for batch interesterification activity (BIU/g). It clarly appears from the figure that the silica carrier with pore size 1500 ⁇ (i.e. 25 times the diameter of the lipase globules), i.e. inside the claimed interval for pore sizes) exhibits an excellent expressed lipase activity at the optimum pH.
- Fig. 2 On Fig. 2 the three of the four immobilized lipase preparations from Fig. 1 which are inside the scope of the present invention were tested in a column in the following manner.
- a system consisting of a precolumn containing ion exchange resin saturated with water and an enzyme column (containing 4.5 g immobilized lipase preparation) in series was set up.
- the function of the precolumn was saturation of the substrate with water.
- An oil mixture consisting of 28.6% (w/w) lauric acid and 71.4% (w/w) soy bean oil was pumped through the columns.
- the temperature in the columns was kept at 60°C.
- the flow rate was adjusted in order to keep a constant conversion of 14% incorporated lauric acid in the soy bean oil.
- TG is an abbreviation for triglyceride.
- silica carrier with pore size 1500 ⁇ performs very well in regard to initial flow rate.
- Immobilized lipase preparations were prepared with Grace 6 as the carrier.
- the lipase was the Humicola lanuginosa lipase. Except for the drying the immobilized preparations were prepared as indicated in relation to Fig. 1, at pH 4.5.
- Example 1 are production examples;
- Example 3, 4, 5, and 6 are application examples, and
- Example 8 is a comparison example.
- This example is a comparison example, due to the fact that the pore diameter of the carrier is less than 5 times the diameter of the lipase globules.
